The purpose of this study is to find out the effects of the diagnostic and formative assessment on elementary science classes. For this purpose, we developed the diagnostic and formative assessment test and provided them to students before giving them the equivalent and learning achievement tests. The results are described as follows: First, for the science class that took the diagnostic assessment; the test provided help in improving the students' learning achievement. Second, for the science class that took the formative assessment; the test did not provide help in improving the students' learning achievement and in improving their openness to learning opportunity only to self-directed learning attitudes. Third, for the science class that were given both the diagnostic and formative assessment test; the tests provided help in improving the students' learning achievement. It also helped in improving their openness to learning opportunity, initiative for learning, and passion for learning except in problem-solving skills on self-directed learning attitude. Therefore, I recommend the utilization of the diagnostic and formative assessment tests be provided to students in order to improve learning achievement and self-directed learning attitudes in science classes.

The purpose of this study is to present a reflective review of the earth and universe units from the revised elementary curriculum of 2007-2015 and suggest changes in the 2022 revised curriculum. For this purpose, we conducted an FGI with earth science educators and elementary school teachers regarding the content elements and system, the achievement standards and inquiry activity composition, and the vertical and horizontal curriculum connectivity. Free response and weighted hierarchical analysis items were incorporated into the FGI to ensure logical consistency of the inductively derived improvement. This analysis revealed that the composition of units by grade group had been unevenly distributed among each of the "earth systems" until the 2015 revised curriculum was finalized. Furthermore, the basic concept was still insufficient. We suggest that achievement standards centered on the learning content and skills must state specific scientific core competencies, and inquiry activities should include rigorous critical thinking, student written responses, and student inquiry and analysis. In the hierarchical analysis items, FGI emphasized the inclusion of essential content elements rather than reduction of content elements, understanding-oriented concept learning rather than interest-centered phenomenon learning, basic concept division learning before integration between subjects, and expanding vertical-horizontal connectivity rather than repeating and advancing learning. There is a limit to the generalizing the suggestions proposed in this study to the common opinion of elementary earth science experts. However, since the main vision of the 2022 revised curriculum is to gather opinions through educational entities' participation in a variety of educational subjects, it is suggested that our results should be incorporated as one of the opinions proposed for the 2022 curriculum revision.

The objective of this study is to investigate the effects of a new learning method called, 'e-Learning,' by applying this method on a middle school science curriculum and study the influence it has on the students’ short and long term memory. The study was performed on two classes of sixth grade students at 'K middle school' in Yangsan. By handing out structured study assignment in e-Learning, I was able to observe how it affected the learners’ short and long term retention. The results of the study were as follows: First, classes that underwent studies using e-Learning did not show any influence on short term retention. Second, e-Learning had positive influence on long term retention. Third, learners who experienced e-Learning had positive cognition on e-Learning.

The purpose of this study is to develope and apply NIE programs related to sub-chapter 'The Change of Weather and Circulation of Water' in 2nd grade science text book of middle school, and thereby to investigate the effects of NIE approach on science-related attitude and teaming achievement of students, and interaction between treatment methods and students' learning ability. Subjects consisted of 2nd grade students of four classes in a girls middle school located at the southern part of Seoul. Four classes were divided into experimental and control groups by two classes randomly. The experimental groups have been instructed on the related-general concepts for six times and then received seven NIE programs developed by researcher for seven times. The control groups have received the instruction through the conventional teaching method. The NIE learning has been progressed following the steps using in the Iowa Chautaugua Program, e.g. invite, explore, propose explanation and solutions, and take action. NIE programs, e.g. project studying, topic studying and a crossword puzzle have been developed and applied using 'science first' approach of the STS instruction. Twenty questions related to social implications of science and leisure interest in science within seven frameworks of TOSRA have been used in this study as an evaluation instrument of science-related attitude. Learning achievement has been evaluated using an instrument developed by researcher. The results of this study can be summarized as follows. (1) NIE approach was more effective in progressing learning achievement of middle school students than conventional teaching method (p<.01). (2) Experimental groups show statistically significant improvement on science-related attitude than control groups (p<.01). There were no significant interactions between treatment methods and students' learning ability on learning achievement and leisure interest in science. The NIE approach were more effective than the conventional one on social implications of science, especially to low ability students.

This study analyzed the result of the National Assessment of Educational Achievement (NAEA) in a Grade 9 Science class. The study first found that the ratio of below basic achievement was 8.1 percent. This means that a large number of middle school students have not reached basic scientific literacy. Second, the ratio of male students in the below basic level was 10.4 percent, which was double the ratio of female students at 5.5 percent. Third, according to the analysis of achievement by gender, female students outperformed male students. In addition, the female students' standard deviation was smaller than that of the male students, and their scaled scores were distributed nearer the average than that of the male students. Furthermore, analysis of achievement by content domains indicated that females outperformed in all content domains including motion and energy, materials, life, and earth sciences. Showing a similar tendency in the behavior domains, females outperformed males in all behavior domains except the understanding domain. Last, for achievement by living area, students living in the middle and small cities showed the highest scaled score, 196.81. Whereas the average scaled score of the students living in the big cities was 196.15; that of the students living in rural areas was 194.86. With respect to the standard deviation, big cities had the largest, 33.73. That of middle and small cities was 33.70, and of rural areas was 32.92. Although students in cities showed higher achievement in science compared to students in rural areas, they had a bigger gap in academic achievement.

This study mainly intended to investigate the relation between scientific inquiry and several entrance exam results of the gifted in earth science gifted program. The scientific inquiry was tested with their experiment designs. Entrance exams included achievement scores, creativity scores, problem solving, and oral test of high ability students. Student entrance scores were used to judge the level of students' competency in science. Recently students' ability of 'doing science' as measured by their designing experiments has been highly appreciated as a criteria of scientifically gifted students. One of the well known tests was Diet Cola Test developed by Fowler(1990). We used it as a test to figure out students' experiment design ability. We selected 22 gifted students in earth science. We compared their entrance test scores and Diet Cola Test results. Based on the comparison results we proposed several guideline of science education program for high ability students.

In this study, we investigated the philosophical background and progress of the 2022 revised curriculum development in the high school earth science field. Research that was not covered in the research report includes the relevance of the transformative competency of OECD Education 2030, and that core ideas and achievement standards are organized around knowledge understanding, process functions, and value attitudes that constitute the learning compass needle. In addition, the composition of core ideas and Earth science electives in light of the understanding-centered curriculum, and IB type inquiry-based teaching and learning. Main research results include that the 2022 revised Earth science curriculum emphasized the student agency to foster the transformative competency and scientific literacy, and the curriculum document system in the field of earth science uses a learning compass needle. In addition, based on the understanding-centered curriculum, core ideas of Earth science were derived, and elective courses were organized to help students reach these core ideas. Also, IB-type inquiry-based teaching and learning was emphasized to foster student agency with knowledge construction competency. Based on the research results, slimming of the national and general level curriculum, the need to develop process-centered assessment methods for value and attitudes, the need for curriculum backward design, and ways to develop student agency through inquiry-based teaching and learning were suggested.

The ability-grouping is the essence of the seventh educational curriculum, applied to school from year 2000, and its enriched-supplementary type will be carried out for science course. This study examines the effect of the enriched-supplementary ability-grouping within class to student's academic achievement and the attitude, related to science. Thus we developed teaching and learning methods with intellectual level about the subject of 'Water Circulation and Weather Change' in Middle-School Science 2. Then we tested 152 eighth graders who were divided into the experimental and control groups. The experimental one was taught through the ability-grouping for about six weeks, while the control through conventional lecture. The improvement of the experimental group in academic achievement was more effective than that of the control, and particularly to below-average students who ranked in lower thirty percent. The experimental one got more negative change in domain 'Science as a Subject, and in subdomain 'Anxiety in Science Lesson'. While outstanding students who ranked in upper thirty percent showed a significant positive change in subdomain 'Satisfaction in Teaching Method, the below-average were negatively changed in subdomain 'Anxiety in Science Lesson'. The current ability-grouping was suitable for the improvement of academic achievement, but not for the general attitude related to science. In order to enhance the ability-grouping effect in science education, we need to additionally consider student's interest and concern in grouping, and develop various teaching and learning methods together with proper textbook contents.

The aim of this study was to find out the effect of instruction with storytelling on the achievement, attitude and interest in science. For this study, two classes were divided into experimental class and comparative class. All the results were analyzed quantitatively. Results of this study can be described as follows. First, the experimental class didn't have a significant difference in scholastic achievement compared with the comparative class. However, the results of the t-test for the academic achievement due to achievement level showed a positive effect in the average level of students. And experimental group was statistically significantly higher in the section of 'Combustion and Extinguishment' than that of the other group. Second, There was a significant difference in the aspect of the effect of instruction with storytelling on the student's science-related attitudes. As a result of analysis by sub categories of science-related attitudes, storytelling was effective in attitude toward science, but no significant differences were found in scientific attitude. Third, instruction with storytelling didn't show a meaningful difference in scientific interest. However, in the sub-part, they showed a meaningful improvement in attention and satisfaction.
